powerpc/boot: Expose Kconfig symbols to wrapper
Currently the wrapper is built without including anything in $(src)/include/, which means there are no CONFIG_ symbols defined. This means the platform specific serial drivers were never enabled. We now copy the definitions into the boot directory, so any C file can now include autoconf.h to depend on configuration options. Fixes: 866bfc75f40e ("powerpc: conditionally compile platform-specific serial drivers") Signed-off-by: Joel Stanley <joel@jms.id.au> [mpe: Fix to use $(objtree) to find autoconf.h] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
